Description Richard W.M. Jones 2012-09-16 22:16:21 UTC

Description of problem:

><fs> inspect-get-arch /dev/sda2
ARM
><fs> file-architecture /bin/ls
ARM
><fs> file /bin/ls
ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=0x1404ac2b8b93ea1fe0d5f8b065dd9c9c5550c581, stripped

Probably should be something like 'armhfp', 'arm5' etc?

Version-Release number of selected component (if applicable):

libguestfs 1.19.40

Seems like we need to patch file utility. Elf file can contain a tag describing CPU architecture (TAG_CPU_name, TAG_CPU_raw_name) and/or needed extension. Howewer, these usually aren't part of ELF file since they are optional.
There is other field called Flags and its meaning is architecture specific, for 32bit ARM it contains EABI version and endianness info, so it doesn't seem to give us info we'd like to have.
